Acronychia oblongifolia, commonly known as white aspen or yellow wood,[2] is a species of shrub to medium-sized rainforest tree of the citrus family, Rutaceae, and is endemic to eastern Australia.It has mostly simple, egg-shaped leaves with the narrower end towards the base, small groups of creamy-white flowers and fleshy, more or less spherical, edible fruit.Flowering occurs from February to June and the fruit is a fleshy, white, yellow or purplish, more or less spherical drupe 5–9 mm (0.2–0.4 in) long, that matures from May to December.Mostly shrubby, the places where Acronychia oblongifolia reaches tree size include the rainforest of the McPherson Range on the New South Wales/Queensland border, and the Mitchell River Gorge in Victoria.[4] Acronychia oblongifolia is fairly readily cultivated in a well-drained soil with a sunny aspect, and benefits from extra water and fertiliser.
